# Thanks chat gippity!
# This zsh function simplifies jumping around many repos. And single repos, too
# It attempts to checkout the current dir's git repo main branch, fetch and pull, and open the directory in VS Code
# If there are unstaged changes in the current branch, it shows a diff and asks y/n if you want to discard those changes
# If yes, it continues as normal (checkout main, fetch, pull, VSC). If no, it aborts
# Why "mupen"? It's some amalgamation of main, pull, and open :shrug:

# Define the function
mupen() {
  # Attempt to checkout the main branch. If there are no changes, this will succeed.
  git checkout main &>/dev/null && {
    echo "Switched to main branch successfully."
    git fetch && git pull
    code .
    return
  }

  # If the checkout fails, it might be due to unstaged changes. Check for unstaged changes.
  if ! git diff --exit-code --quiet; then
    echo "Unstaged changes detected."
    git diff
    
    # Ask the user if they want to discard the changes.
    read "response?Do you want to discard these changes? [y/N]: "
    if [[ "$response" =~ ^[Yy]$ ]]; then
      # Discard the changes
      git checkout -- .
    else
      # Exit if the user doesn't want to discard the changes.
      echo "Exiting without discarding changes."
      return

  # Checkout the main branch, fetch and pull updates, and open VS Code.
